CONNECTION
Before the generator can be connected to a building’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the building’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power supply has failed or has been turned off for line repair.
Backfeeding can electrocute or injure line maintenance personnel. Also, generator and building
electrical system damage can occur when normal
operating power returns if unit is used without an
isolation switch.
AE00086
EXTENSION CORD NOTES
Extension cords should be protected by a tough flexible
rubber sheath (IEC 245) or the equivalent to withstand
mechanical stresses.

9 Do not overload. The total load of all electrical appliances must not exceed the
supply range of the generator. Overloading will damage the generator.
9 When supplying precision equipment, electronic controllers, PCs, electronic
computers, microcomputer-based equipment or battery chargers, keep the
generator a sufficient distance away to prevent electrical interference from the
engine. Also ensure that electrical noise from the engine does not interfere
with any other electrical devices located near the generator.
9 If the generator is to supply medical equipment, advice should first be obtained
from the manufacturer, a medical professional or hospital.
9 Some electrical appliances or general-purpose electric motors have high start-
ing currents, and cannot therefore be used, even if they lie within the supply
ranges given in the above table. Consult the equipment manufacturer for further advice.

WARRANTY QUESTIONS AND ANSWERS
Q. What costs are my responsibility during the
warranty period?
A. The customer’s responsibility includes all
costs of normal maintenance service, non-
warranty repairs, accident damages, as well
as oil and spark plugs.
Q. What are some examples of “abnormal” strain,
neglect, or abuse?
A. These terms are general and overlap each
other in areas. Specific examples include:
Running the machine out of oil; lack of proper
maintenance; operating the machine with a
broken or damaged part which causes anoth-
er part to fail; and so on. If you have any
specific questions on operation or mainte-
nance, please contact your dealer for advice.
Q. Does the warranty cover incidental costs such
as transportation due to a failure?
A. No. The warranty is limited to repair of the
machine itself.
Q. May I perform any or all of the recommended
maintenance shown in the Owner’s Manual
instead of having the dealer do them?
A. Yes, if you are a qualified mechanic and follow
the procedures specified in the Owner’s and
Service Manual. We do recommend, however,
that items requiring special tools or equipment
be done by a Yamaha generator dealer.
Q. Will the warranty be void or cancelled if I do
not operate or maintain my new Yamaha
exactly as specified in the Owner’s Manual?
A. No. The warranty on a new Yamaha cannot
be “voided” or “cancelled.”
However, if a particular failure is caused by
operation or maintenance other than as
shown in the Owner’s Manual, that failure
may not be covered under warranty.
Q. What responsibility does my dealer have
under this warranty?
A. Each Yamaha generator dealer is expected
to:
1. Check the operation of the generator
before sale.
2. Explain the operation, maintenance, and
warranty requirements to your satisfaction
at the time of sale, and upon your request
at any later date.
In addition, each Yamaha generator dealer is
held responsible for his setup, service and
warranty repair work.
Q. Is the warranty transferable to second own-
ers?
A. Yes. The remainder of the existing warranty
can be transfered upon request.
The unit has to be inspected and reregistered
by an authorized Yamaha generator dealer for
the policy to remain effective.

YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board and Yamaha Motor Corporation, U.S.A. are pleased to explain the
emission control system warranty on your 2008 and later Small Off Road Engine (SORE). In California,
new SORE engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. Yamaha must warrant the emission control system on your SORE engine for the periods of time
listed below provided there has been no abuse, neglect or improper maintenance of your SORE engine.
Your emission control system may include parts such as the carburetor or fuel-injection system, the ignition system, and catalytic converter. Also included may be hoses, belts, connectors and other emissionrelated assemblies.
Where a warrantable condition exists, Yamaha will repair your SORE engine at no cost to you including
diagnosis, parts and labor.
MANUFACTURER’S WARRANTY COVERAGE
The 2008 and later SORE engines are warranted for two years. If any emissions-related part on your
engine is defective, the part will be repaired or replaced by Yamaha.
OWNER’S WARRANTY RESPONSIBILITIES
9 As the SORE engine owner, you are responsible for the performance of the required maintenance
listed in your owner’s manual. Yamaha recommends that you retain all receipts covering maintenance
on your SORE engine, but Yamaha cannot deny warranty solely for the lack of receipts or for your
failure to ensure the performance of all scheduled maintenance.
9 As the SORE engine owner, you should however be aware that Yamaha may deny you warranty cov-
erage if your SORE engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
9 You are responsible for presenting your SORE engine to a Yamaha dealer as soon as a problem
exists. The warranty repairs should be completed in a reasonable time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities, you should contact the
Yamaha Customer Relations Department at 1-800-962-7926.
Yamaha Motor Corporation, U.S.A. warrants to the ultimate purchaser and each subsequent purchaser
thereafter that each new SORE engine certified for sale and registered in California are:
1. Designed, built, and equipped so as to conform, at the time of sale, with all applicable regulations
adopted by the California Air Resources Board, and
2. All warranted parts are free from defects in material and workmanship for the warranty period of the
SORE engine or the period prior to the first scheduled replacement point of the warranted part as
required by the maintenance schedule, if applicable, whichever is less. A defect exists when a deficiency in material or workmanship is such that an emission-related warranted part does not function
as designed.
The warranty period begins on the date that the SORE engine is delivered to an ultimate purchaser or on
the date it is first placed in service.
The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the written
– 47 –
Page 53
instructions required by subsection (d) must be warranted for the warranty period defined in
Subsection (b)(2). If any such part fails during the period of warranty coverage, it must be repaired or
replaced by the manufacturer according to Subsection (4) below. Any such part repaired or replaced
under the warranty must be warranted for the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the written instructions required by
subsection (d) must be warranted for the warranty period defined in Subsection (b)(2). A statement in
such written instructions to the effect of “repair or replace as necessary” will not reduce the period of
warranty coverage. Any such part repaired or replaced under warranty must be warranted for the
remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the written instruc-
tions required by subsection (d) must be warranted for the period of time prior to the first scheduled
replacement point for that part. If the part fails prior to the first scheduled replacement, the part must
be repaired or replaced by the engine manufacturer according to Subsection (4) below. Any such
part repaired or replaced under warranty must be warranted for the remainder of the period prior to
the first scheduled replacement point for the part.
(4) Repair or replacement of any warranted part under the warranty must be performed at no charge to
the owner at a warranty station.
(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs must be provid-
ed at all manufacturer distribution centers that are franchised to service the subject engines.
(6) The owner must not be charged for diagnostic labor that leads to the determination that a warranted
part is in fact defective, provided that such diagnostic work is performed at a warranty station.
(7) The manufacturer is liable for damages to other engine components proximately caused by a failure
under warranty of any warranted part.
(8) Throughout the emissions warranty period defined in Subsection (b)(2), the manufacturer must main-
tain a supply of warranted parts sufficient to meet the expected demand for such parts.
(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and
must be provided without charge to the owner. Such use will not reduce the warranty obligations of
the manufacturer.
(10)Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The
use of any non-exempted add-on or modified parts will be grounds for disallowing a warranty claim.
The manufacturer will not be liable to warrant failures of warranted parts caused by the use of a nonexempted add-on or modified part.
(11)The manufacturer issuing the warranty shall provide any documents that describe that manufacturer’s
warranty procedures or policies within five working days of request by the Air Resources Board.

DURING THE PERIOD OF THIS WARRANTY
Yamaha Motor Corporation, U.S.A. will repair or replace any warranted part deemed defective by Yamaha
during the scope of the warranty without charge to the owner, including parts, labor, and diagnosis. This
work must be done at an authorized Yamaha dealer. Give notice to an authorized Yamaha dealer of any
apparent defects(s) within a reasonable period of time after discovery. The SORE engine must be made
available for inspection by an authorized Yamaha dealer.
OWNER’S RESPONSIBILITY:
The owner of the SORE engine is responsible for the performance of required maintenance (see your
Owner’s Manual). Receipts and maintenance records covering the performance of regular maintenance
should be retained in the event questions arise concerning maintenance. The receipts should be transferred to each subsequent owner of this SORE engine.
The emission control systems of your Yamaha SORE engine were designed, built, tested, and certified as
being in conformity with California emission control regulations using genuine Yamaha parts. Accordingly,
it is recommended that any replacement part(s) used for maintenance, replacement, or repair of emission
control systems be Yamaha parts. The owner may elect to have maintenance, replacement, or repair of
the emission control devices and systems performed by any repair establishment or individual, and may
elect to use parts other than Yamaha parts for such maintenance, replacement, or repair without invalidating this warranty. However, the cost of such service or parts will not be covered under the warranty.
EXCLUSIONS: No warranty coverage will be allowed if the part(s) failure was caused by owner/operator
abuse, neglect, tampering, improper adjustment unless performed by a dealer during warranty repair
work, modification, misuse, alteration, or improper maintenance (see your Owner’s Manual).
Use of parts which are not qualitatively equivalent to genuine Yamaha parts, improper service, or lack of
required maintenance which causes failure of a warranted part may constitute abuse and/or improper service, thereby invalidating warranty liability hereunder.
